The use of tissue engineering to repair large osteochondral defects has been impeded by the limited regenerative capacity of cartilage. Herein, we describe the local release of bone morphogenetic protein 7 (BMP-7) to stimulate the bone marrow-derived progenitors to repair osteochondral defects. BMP-7-releasing poly(D,L-lactide-co-glycolide) (PLGA) matrix(More)
[Purpose] This study was performed to investigate the changes in the body balance index when spiral taping is applied to the neck and ankle. The findings are expected to serve as evidence of the usefulness of taping the neck instead of the ankle when ankle taping is not feasible in clinical practice. [Subjects and Methods] Twenty healthy male students at A(More)
Mesenchymal cells condensation is crucial in chondrogenic development. However current tissue-engineered scaffolds for chondrogenesis pay little attention to this phenomenon. In this study, we fabricate poly(l-lactide-co-glycolide) (PLGA)/poly(l-lactide) (PLLA) microfiber scaffolds and coat them with human fibroblast-derived matrix (hFDM) that is a(More)
Carbon-coated SnO2 nano-composite was synthesized by using a hydrothermal method in a one step process with sizes of 1 to 3 microm. The carbon-coated SnO2 nano-composite was easily obtained by changing firing atmosphere from air to argon (600 degrees C for 3 hours). The carbon-coating thickness and size of the SnO2 nanoparticles in carbon-coated SnO2(More)
Violent games have increasingly gained their market share in recent video game markets. They have attracted much attention due to their potential effects on users in advertising and aggression. However, little research has investigated such effects considering both user aggression and persuasion mechanism in virtual space. Based on the general aggression(More)
